By the time Windows 10 1507 slips off the list, it will have been supported for about 21 months. Part of the reason it lasted longer than Microsoft’s stated norm was because the firm issued just one feature upgrade—v. 1607—in 2016.

That’s because Microsoft has committed to simultaneously supporting just two Current Branch for Business (CBB) builds. At the release of N+2 onto CBB, the company starts a 60-day-or-so countdown. At the end of the 60 days, N drops off the support list. N+1 then becomes N and N+2 morphs into N+1.
